Charlie Sheen showed off his 1927 World Series ring yesterday when he returned to work (with his hot new girlfriend in tow), which he purchased for a cool quarter of a million dollars.

An avid baseball fan, Charlie has portrayed baseball players in not just Eight Men Out (which dramatized the 1919 Chicago White Sox World Series scandal) but also in Major League and Major League II.

Charlie recently spoke about his desire to reprise his role as Rick "Wild Thing" Vaughn in a third Major League film, as soon as producers are ready to greenlight a script.

Sources told TMZ that there is, in fact, an outline for the film in place, and that most of the original cast has been contacted to return, except for Corbin Bernsen, who played Roger Dorn in the first three films.

Sheen is campaigning for Corbin's return, saying, "I would love it for him to be in ... but I ain't the writer or director ... I'm a hired gun ... I'll do my best."

The Two and a Half Men star entered rehab last month after being rushed to the hospital with abdominal pain. Charlie rehabbed at home and returned to work yesterday looking as energetic as ever.

Earlier this month, Sheen attended batting practice at UCLA with some major league pitchers, and even had the chance to dole out his own form of advice to the college team: "Stay off the crack. Drink a chocolate milk. Enjoy your moment. That's all I got."

Charlie also apparently had a Major League party last weekend, which included not only several major leaguers who were flown in by Charlie on private jet, but also a screening of his Major League film at home. Maybe baseball is the best medicine for Charlie!
